1 1999 International SOLING Class Rules I S A F Authority* : International Sailing Federation * The International Sailing Federation (ISAF) is not a National Authority (NA).

2 International SOLING Class Rules The Soling was designed in 1965 by Jan Linge and was adopted as an international class in PART I ADMINISTRATION Section A General A.1 Type of Class Rules A.1.1 A.1.2 These are closed class rules. This is a One-Design Class. These rules and the official plans are intended to ensure that boats of this Class are as nearly alike as possible as regards shape and weight of hull and decking, shape and weight of keel, shape of rudder, shape and area of sail plan and in some other items which affect performance. All boats shall be built in accordance with the plans, with the exception of spars, standing and running rigging, sheeting arrangements, rudder stock with bearing, tiller and tiller extension, lifting eyes, cleats and fairleads. These items and their fittings need not comply with the official plans but shall, in some cases, be controlled in other ways by the following rules. A.2 Language A.2.1 A.2.2 The official language of the class is English and in case of dispute over translation the English text shall prevail. The word «shall» is mandatory and the word «may» is permissive. A.3 Abbreviations A.3.1 ISAF International Sailing Federation MNA ISAF Member National Authority ISA International Soling Class Association NSA National Soling Association ERS Equipment Rules of Sailing RRS Racing Rules of Sailing A.4 Authorities and responsibilities A.4.1 A.4.2 A.4.3 The international authority of the class is the ISAF which shall co-operate with the ISA in all matters concerning these class rules. The ISAF, an MNA, the ISA, an NSA or an official measurer is under no legal responsibility in respect of these class rules. Notwithstanding anything contained herein, the MNA has the authority to withdraw a certificate and shall do so on the request of the ISAF. 2 Soling Class Rules 1999

3 A.5 Administration of the Class A.5.1 A.5.2 ISAF has delegated its administrative functions of the Class to MNAs. The MNA may delegate part or all of its functions, as stated in these class rules, to an NSA. In countries where there is no MNA, or the MNA does not wish to administrate the class, its functions as stated in these class rules shall be carried out by the ISA which may delegate the administration to an NSA. A.6 ISAF Rules A.6.1 These class rules shall be read in conjunction with the ERS and measurements shall be taken in accordance with these unless specified. Where a term is used in its defined sense, it is printed in «bold» type if defined in the ERS and in «italic» type if defined in the RRS. A.7 Amendments to Class Rules A.7.1 Amendments to these class rules shall be proposed by the ISA, or an MNA, and shall be approved by the ISAF. A.8 Interpretation of Class Rules - General A.8.1 Interpretations of class rules except as provided by A.9, shall be made by the ISAF. Request for interpretation shall be made in accordance with the ISAF regulations. A.9 Interpretation of the Class Rules - at an Event A.9.1 Any interpretation of class rules required at an event may be by an international jury constituted in accordance with the RRS, Appendix Q. Such interpretation shall only be valid during the event and the organising authority shall, as soon as practical after the event, inform the ISAF, the MNA and the ISA of such an interpretation. A.10 International Class Fee and ISAF Plaque A.10.1 The International Class Fee shall be paid by the licenced hull manufacturer to the ISAF. A.10.2 The ISAF shall after having received the International Class Fee for the hull, send the ISAF Building Plaque and a measurement form to the licenced hull builder. A.10.3 Builders shall be licenced by ISAF Limited, and shall only obtain GRP plugs and/or production moulds and templates from suppliers approved by the ISAF. Licences shall be issued after consultation with the ISA. Soling Class Rules

4 A.11 Identification on Sail A.11.1 Sail numbers shall be issued by the MNA. A.11.2 The method of allocating registration numbers shall be at the discretion of the MNA or its appointed representative, provided that the same number shall never be allocated to two boats of the same nationality at the same time. A.11.3 The MNA shall inform the ISA of the names and addresses of owners of boats issued with sail numbers. A.12 Certification A.12.1 The certificate shall be obtainable from the MNA in the following way: a) In the case of a new boat, or one so substantially reconstructed or repaired (hull, keel or corrector weight) as to require re-measurement, the completed measurement form, together with any registration fee that may be required, shall be sent to the MNA in the country where the boat is to be registered, b) In the case of change of ownership by sending the invalid certificate to the MNA for endorsement with any re-registration fee that may be required. A new measurement certificate shall then be issued to the new owner. A.12.2 Upon receipt of a satisfactorily completed measurement form the MNA may issue a measurement certificate. The MNA shall retain a copy of the measurement certificate and of the measurement form. A.12.3 The measurement certificate (as required by Rule 78.1 of the RRS) shall be: a) The original measurement form or a certified true copy, which shall have been stamped by the MNA. Measurement Forms in loose pages shall be identified and signed on each page by the Measurer, b) The official measurement certificate issued by the ISAF/ISA or a similar certificate (with all the items of the official certificate) issued by an MNA. A.12.4 All certified boats shall be liable to re-measurement at any time on protest or at the discretion of the ISAF, the MNA, ISA, NSA or the Race Committee. A.12.5 If a builder is found to have signed a measurement form for a boat that did not measure correctly, he shall be liable to rectify the error, and may have his licence as a builder withdrawn. A.12.6 Any re-measurement shall be in accordance with the current Class Rules except for the following Rules: C.4.3, C.9.8, D.3.2.4, E.3.1.3, E.3.4.2, F (a) to (d). Only the foregoing exceptions may, at the owner's option, be in accordance with either the current class rules or the rules in force when the measurer signed the original measurement form. All replacement equipment shall comply with the class rules in force at the time the replacement is made. A.12.7 In the event of re-measurement of a sail such re-measurement shall be in accordance with the current class rules. 4 Soling Class Rules 1999

5 A.12.9 A measurer, either on the first measurement or subsequently, may take random drillings to verify that the specifications of the laminates in the construction plans for the hull or decking or other specifications contained in these rules have been complied with. Such drillings shall be of the minimum size required to verify compliance and shall only be taken if no other adequate method of verification is available. A If it is considered that there has been any attempt to depart from the design or these rules in any particulars, it shall be reported to the MNA, which shall withhold the certificate of measurement pending an examination of the case. The MNA may grant a certificate if approval is obtained from the ISAF in consultation with the ISA. A.13 Measurers A.13.1 Fundamental measurement shall only be carried out by an official measurer. Section B Boat Eligibility For a boat to be eligible to race the rules in this section shall have been complied with.
